But only one building sustained about $1,500 of damage to its roof, Costa Mesa fire Chief Dan Stefano said. No injuries were reported.

Crews were expected to remain at the park through Friday evening, mopping up and keeping an eye on hot spots.

Authorities ordered no evacuations, Sherwood said, but some affected residents reportedly grabbed belongings and left their homes anyway.

Newport Beach resident Debbie Land said her neighbors on the northern part of Starfish Court, a section of Newport adjacent to Talbert, decided to find a safer place to wait out the situation.

Land said she lives farther south on Starfish, where "people on my end [were] getting pets in their cars and getting their stuff" in case they had to evacuate.

After seeing the smoke, Costa Mesa resident Rafael Davila headed down Victoria and onto the Santa Ana River trail, where dozens of onlookers stood on the Costa Mesa and Huntington Beach sides of the riverbed. Using his iPhone, Davila took a selfie video of the OCFA helicopter filling up water at Victoria Pond before it headed out to douse the fire.

Costa Mesa police closed the eastbound lanes of Victoria Street, starting at Brookhurst Street in Huntington Beach, during the fire. Canyon Drive and Valley Road, south of Victoria Street in Costa Mesa, were also shut down.

Newport Beach police officers closed off the end of West 19th Street for a time.

The fire produced enough smoke and ash that Friday's Estancia High School baseball game against Saddleback High School in Santa Ana was postponed due to air quality, according to Coach Nate Goellrich.

In January, four fires broke out in the northern end of Talbert Park and Fairview Park within the span of two days. Investigators concluded the incidents were "definitely arson." No suspects have been identified.

Anyone with information about Friday's fire is asked to call the Costa Mesa Fire Department at (714) 754-5106.
